Description
Technical field
The information that the present invention relates to is transmitted the field, in particular to a kind of picture channel and information transmitting methods thereof.
Background technology
Existing bill is when the information of transmission, and to the paper of bill, the information character on the paper comprises Chinese character, numeral, letter and other punctuation mark to the information character that is transmitted by the computer system control printer prints; These characters can when the needs computer system is discerned, generally be used a kind of OCR (Optical Character Recognition by people's direct reading identification; Optical character identification) technology; Earlier use scanner scanning to import computer system as picture file bill, computer system starting moves a kind of OCR software program image is discerned processing, and the information on the OCR software program output bill supplies computer system to use; This belongs to a kind of information processing of robotization; Information exchanging process need not be by personnel's input information, and the thing that personnel do is some back works, for example bill is put into scanner; Start computer power supply, start functional performances such as relevant software programs.Under this use pattern, when the bill paper is a simply connected, when printing type is any printing technique commonly used such as laser, ink-jet, temperature-sensitive, hot transfer printing; All have no problem, when the bill paper was join more, the paper material can be used NCR; Each couplet of NCR all scribbles one deck carbon ink, when being under pressure, can stay the vestige of pressure spot on paper, when this multiple part bills uses several the printing techniques in front to print; Because printing principle is not that physics formula low-pressure knocks printing, so first can be printed and go up content, the back is several then can be blank; This situation can not satisfy user demand, improve, and needs to use stylus printer; Stylus printer knocks colour band through pin information is printed on the paper, since the characteristics of the transmission of percussion power and NCR, several strokes that all characters also can occur in the back of multiple part bills; Form the same complete information with first, this multiple part bills is in people's Direct Recognition; Or computer system is when using the identification of OCR technology, but each joins all Direct Recognition.Obtaining information with computer system is example, and this information exchanging process is that input information arrives image output information again to paper.
Technical characterictic and the implementation of existing bar-code label technology when the information of transmission is; With information coding with print on the label, what PRN device used is the bar code dedicated printer by bar code printing software, and printing principle is hot transfer printing; Bar code printing to the label after; The people not directly discerns, and the barcode scanner that needs to use barcode scanner just to be commonly called as is swept bar code, and barcode scanner is aimed at the bar code on the bar-code label; Barcode scanner can be sent the information that identifies into computer system through the data line that carries and supplies further to use and handle under the identification case of successful, such information exchanging process be information to bar code to label to barcode scanner to information.
